1 INDICATIONS AND USAGE Hydrocodone bitartrate and homatropine methylbromide is indicated for the symptomatic relief of cough in adult patients 18 years of age and older. Limitations of Use : Not indicated for pediatric patients under 18 years of age [see Use in Specific Populations (8.4) ] . Contraindicated in pediatric patients less than 6 years of age [see Contraindications (4) ] . Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration, and persist over the course of therapy [see Warnings and Precautions (5.1) ], reserve hydrocodone bitartrate and homatropine methylbromide for use in adult patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of cough. Hydrocodone bitartrate and homatropine methylbromide is a combination of hydrocodone, an opioid agonist; and homatropine, a muscarinic antagonist, indicated for the symptomatic relief of cough in adult patients 18 years of age and older. ( 1 ) Limitations of Use Not indicated for pediatric patients under 18 years of age. ( 1 ) Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy, reserve hydrocodone bitartrate and homatropine methylbromide for use in adult patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of cough. ( 1 , 5.1 )

2 DOSAGE AND ADMINISTRATION Adults 18 years of age and older : One (1) tablet or 5 mL of the oral solution every 4 to 6 hours as needed; not to exceed six (6) tablets or 30 mL in 24 hours. ( 2.2 ) Measure hydrocodone bitartrate and homatropine methylbromide oral solution with an accurate milliliter measuring device. ( 2.1 , 5.5 ) Do not increase the dose or dosing frequency. ( 2.1 ) Prescribe for the shortest duration consistent with treatment goals. ( 2.3 ) Reevaluate patients with unresponsive cough in 5 days or sooner for possible underlying pathology. ( 2.3 ) Reevaluate patient prior to refilling. ( 2.3 ) Do not rapidly reduce or abruptly discontinue in a physically-dependent patient. ( 2.3 ) 2.1 Important Dosage and Administration Instructions Administer hydrocodone bitartrate and homatropine methylbromide by the oral route only. Always use an accurate milliliter measuring device when administering hydrocodone bitartrate and homatropine methylbromide oral solution to ensure that the dose is measured and administered accurately. A household teaspoon is not an accurate measuring device and could lead to overdosage [see Warnings and Precautions (5.5) ] . For prescriptions where a measuring device is not provided, a pharmacist can provide an appropriate measuring device and can provide instructions for measuring the correct dose. Do not overfill. Rinse the measuring device with water after each use. Advise patients not to increase the dose or dosing frequency of hydrocodone bitartrate and homatropine methylbromide because serious adverse events such as respiratory depression may occur with overdosage [see Warnings and Precautions (5.2) , Overdosage (10) ] . The dosage of hydrocodone bitartrate and homatropine methylbromide should not be increased if cough fails to respond; an unresponsive cough should be reevaluated for possible underlying pathology [see Dosage and Administration (2.3) , Warnings and Precautions (5.4) ] . 2.2 Recommended Dosage Adults 18 years of age and older : One (1) tablet or 5 mL of the oral solution every 4 to 6 hours as needed; not to exceed six (6) tablets or 30 mL in 24 hours. 2.3 Monitoring, Maintenance, and Discontinuation of Therapy Prescribe hydrocodone bitartrate and homatropine methylbromide for the shortest duration that is consistent with individual patient treatment goals [see Warnings and Precautions (5.1) ]. Monitor patients closely for respiratory depression, especially within the first 24 to72 hours of initiating therapy [see Warnings and Precautions (5.2) ]. Reevaluate patients with unresponsive cough in 5 days or sooner for possible underlying pathology, such as foreign body or lower respiratory tract disease [see Warnings and Precautions (5.4) ] . If a patient requires a refill, reevaluate the cause of the cough and assess the need for continued treatment with hydrocodone bitartrate and homatropine methylbromide, the relative incidence of adverse reactions, and the development of addiction, abuse, or misuse [see Warnings and Precautions (5.1) ] . Do not rapidly reduce or abruptly discontinue hydrocodone bitartrate and homatropine methylbromide in a physically-dependent patient [see Drug Abuse and Dependence (9.3) ] . When a patient who has been taking hydrocodone bitartrate and homatropine methylbromide regularly and may be physically dependent no longer requires therapy with hydrocodone bitartrate and homatropine methylbromide, taper the dose gradually, by 25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both.

Because these reactions may be reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The most common adverse reactions to hydrocodone bitartrate and homatropine methylbromide include: Sedation (somnolence, mental clouding, lethargy), impaired mental and physical performance, lightheadedness, dizziness, headache, dry mouth, nausea, vomiting, and constipation. Other reactions include: Anaphylaxis : Anaphylaxis has been reported with hydrocodone, one of the ingredients in hydrocodone bitartrate and homatropine methylbromide. Body as a whole : Coma, death, fatigue, falling injuries, lethargy. Cardiovascular : Peripheral edema, increased blood pressure, decreased blood pressure, tachycardia, chest pain, palpitation, syncope, orthostatic hypotension, prolonged QT interval, hot flush. Central Nervous System : Facial dyskinesia, insomnia, migraine, increased intracranial pressure, seizure, tremor. Dermatologic : Flushing, hyperhidrosis, pruritus, rash. Endocrine/Metabolic : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs. Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Cases of androgen deficiency have occurred with chronic use of opioids. Gastrointestinal : Abdominal pain, bowel obstruction, decreased appetite, diarrhea, difficulty swallowing, dry mouth, GERD, indigestion, pancreatitis, paralytic ileus, biliary tract spasm (spasm of the sphincter of Oddi).

7 DRUG INTERACTIONS No specific drug interaction studies have been conducted with Hydrocodone Bitartrate and Homatropine Methylbromide Tablets. Serotonergic Drugs : Concomitant use may result in serotonin syndrome. Discontinue if serotonin syndrome is suspected. ( 7.5 ) Monoamine Oxidase Inhibitors (MAOIs) : Can potentiate the effects of hydrocodone. Avoid concomitant use in patients receiving MAOIs or within 14 days of stopping an MAOI. ( 7.6 ) Muscle Relaxants : Avoid concomitant use. ( 7.7 ) Diuretics : Hydrocodone may reduce the efficacy of diuretics. Monitor for reduced effect. ( 7.8 ) Anticholinergic drugs : Concurrent use may cause paralytic ileus. ( 5.9 , 7.9 ) 7.1 Alcohol Concomitant use of alcohol with Hydrocodone Bitartrate and Homatropine Methylbromide Tablets can result in an increase of hydrocodone plasma levels and potentially fatal overdose of hydrocodone. Instruct patients not to consume alcoholic beverages or use prescription or nonprescription products containing alcohol while on Hydrocodone Bitartrate and Homatropine Methylbromide Tablets therapy [ see Warnings and Precautions (5.8) and Clinical Pharmacology (12.3) ]. 7.2 Inhibitors of CYP3A4 and CYP2D6 The concomitant use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets and CYP3A4 inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), or protease inhibitors (e.g., ritonavir), can increase the plasma concentration of hydrocodone, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after a stable dose of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets are achieved [ see Warnings and Precautions (5.7) ]. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the hydrocodone plasma concentration will decrease [ see Clinical Pharmacology (12.3) ], resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to hydrocodone. Avoid the use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets while taking a CYP3A4 or CYP2D6 inhibitor. If concomitant use is necessary, monitor patients for respiratory depression and sedation at frequent intervals. 7.3 CYP3A4 Inducers The concomitant use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets and CYP3A4 inducers such as rifampin, carbamazepine, or phenytoin, can decrease the plasma concentration of hydrocodone [ see Clinical Pharmacology (12.3) ], resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to hydrocodone [ see Warnings and Precautions (5.7) ]. After stopping a CYP3A4 inducer, as the effects of the inducer decline, the hydrocodone plasma concentration will increase [ see Clinical Pharmacology (12.3) ], which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. Avoid the use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets in patients who are taking CYP3A4 inducers. If concomitant use of a CYP3A4 inducer is necessary, follow the patient for reduced efficacy. 7.4 Benzodiazepines, and Other CNS Depressants Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, and other opioids, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death. Avoid the use of Hydrocodone Bitartrate and Homatropine Methylbromide Tablets in patients who are taking benzodiazepines or other CNS depressants [ see Warnings and Precautions (5.8) ], and instruct patients to avoid consumption of alcohol while on Hydroc …

8 USE IN SPECIFIC POPULATIONS Pregnancy : Avoid use in pregnant women. May cause fetal harm. ( 8.1 ) Lactation : Breast-feeding not recommended. ( 8.2 ) Renal Impairment : Use with caution in patients with severe renal impairment. ( 8.6 ) Hepatic Impairment : Use with caution in patients with severe hepatic impairment. ( 8.7 ) 8.1 Pregnancy Risk Summary Hydrocodone Bitartrate and Homatropine Methylbromide Tablets are not recommended for use in pregnant women, including during or immediately prior to labor. Prolonged use of opioids during pregnancy may cause neonatal opioid withdrawal syndrome [ see Warnings and Precautions (5.13) , Clinical Considerations ]. There are no available data with Hydrocodone Bitartrate and Homatropine Methylbromide Tablets use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. Published studies with hydrocodone have reported inconsistent findings and have important methodological limitations ( see Data ). Reproductive toxicity studies have not been conducted with Hydrocodone Bitartrate and Homatropine Methylbromide Tablets; however, studies are available with individual active ingredients or related active ingredients ( see Data ). In animal reproduction studies, hydrocodone administered by the subcutaneous route to pregnant hamsters during the period of organogenesis produced a teratogenic effect at a dose approximately 45 times the maximum recommended human dose (MRHD) ( see Data ). Based on the animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [ see Warnings and Precautions (5.13) ]. Labor or Delivery Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid antagonist, such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate. Opioids, including Hydrocodone Bitartrate and Homatropine Methylbromide Tablets, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioids during labor for signs of excess sedation and respiratory depression. Data Human Data Hydrocodone A limited number of pregnancies have been reported in published observational studies and postmarketing reports describing hydrocodone use during pregnancy. However, these data cannot definitely establish or exclude any drug-associated risk during pregnancy. Methodological limitations of these observational studies include small sample size and lack of details regarding dose, duration and timing of exposure. Animal Data Reproductive toxicity studies have not been conducted with Hydrocodone Bitartrate and Homatropine Methylbromide Tablets; however, studie …

12.1 Mechanism of Action Hydrocodone Hydrocodone is an opioid agonist with relative selectivity for the mu-opioid receptor, although it can interact with other opioid receptors at higher doses. The precise mechanism of action of hydrocodone and other opiates is not known; however, hydrocodone is believed to act centrally on the cough center. In excessive doses, hydrocodone will depress respiration. Homatropine Homatropine is an anticholinergic that inhibits activity of the muscarinic acetylcholine receptor with less potency than atropine.

11 DESCRIPTION Hydrocodone bitartrate and homatropine methylbromide tablets and oral solution contain hydrocodone, an opioid agonist; and homatropine, a muscarinic antagonist. Each tablet or spoonful (5 mL) of hydrocodone bitartrate and homatropine methylbromide contains 5 mg of hydrocodone bitartrate, USP and 1.5 mg of homatropine methylbromide, USP, for oral administration. Hydrocodone bitartrate and homatropine methylbromide tablets also contain: calcium phosphate dibasic, colloidal silicon dioxide, lactose, magnesium stearate, pregelatinized starch and stearic acid. Hydrocodone bitartrate and homatropine methylbromide oral solution also contains: anhydrous citric acid, FD&C Red 40, methylparaben, natural and artificial cherry flavor, propylparaben, purified water, sorbitol solution, sodium citrate dihydrate and sucrose. Hydrocodone Bitartrate The chemical name for hydrocodone bitartrate is morphinan-6-one, 4,5-epoxy-3-methoxy-17-methyl-, (5α)-, [R-(R*,R*)]-2,3-dihydroxybutanedioate (1:1), hydrate (2:5). It is also known as 4,5α-Epoxy-3-methoxy-17-methylmorphinan-6-one tartrate (1:1) hydrate (2:5). It occurs as a fine white crystal or crystalline powder, which is derived from the opium alkaloid, thebaine. It has a molecular weight of 494.50 and has the following chemical structure: C 18 H 21 NO 3 ∙ C 4 H 6 O 6 ∙ 21⁄2H2O MW 494.490 Homatropine Methylbromide The chemical name for homatropine methylbromide is 8-Azoniabicyclo [3.2.1]octane,3-[(hydroxyphenyl-acetyl)oxy]-8,8-dimethyl-,bromide, endo-. It occurs as a white crystal or fine white crystalline powder. It has a molecular weight of 370.29 and has the following chemical structure: C 17 H 24 BrNO 3 HOMATROPINE METHYLBROMIDE Chemical Structure - Molecular Weight of 494.50 Chemical Structure - Molecular Weight of 370.29

10 OVERDOSAGE Clinical Presentation Hydrocodone Acute overdose with hydrocodone is characterized by respiratory depression (a decrease in respiratory rate and/or tidal volume, Cheyne-Stokes respiration, cyanosis), extreme somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, partial or complete airway obstruction, atypical snoring, hypotension, hypoglycemia, circulatory collapse, cardiac arrest, and death. Toxic leukoencephalopathy has been reported after opioid overdose and can present hours, days, or weeks after apparent recovery from the initial intoxication. Hydrocodone may cause miosis, even in total darkness. Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origin may produce similar findings). Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2)] . Homatropine Homatropine has broad, nonspecific anticholinergic / antimuscarinic activity that similar to, although less potent than, atropine. Overdosage of homatropine can cause mydriasis and cycloplegia (fixed and dilated pupils), dry mouth and eyes, decreased sweating, hyperthermia, flushing, headache, visual blurring, gastrointestinal symptoms, constipation, urinary retention, tachycardia and palpitations, anxiety, restlessness, agitation, hallucinations, convulsions, cardiac arrhythmias and coma. Anticholinergic agents can also precipitate acute narrow angle glaucoma. Treatment of Overdose Treatment of overdosage is driven by the overall clinical presentation, and consists of discontinuation of hydrocodone bitartrate and homatropine methylbromide together with institution of appropriate therapy. Give primary attention to the reestablishment of adequate respiratory exchange through provision of a patent and protected airway and the institution of assisted or controlled ventilation. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. Gastric emptying may be useful in removing unabsorbed drug. For clinically significant respiratory or circulatory depression secondary to hydrocodone overdose, administer an opioid opioid overdose reversal agent such as naloxone or nalmefene. An opioid overdose reversal agent should not be administered in the absence of clinically significant respiratory depression. Because the duration of opioid reversal is expected to be less than the duration of action of hydrocodone in hydrocodone bitartrate and homatropine methylbromide, carefully monitor the patient until spontaneous respiration is reliably reestablished. If the response to an opioid overdose reversal agent is suboptimal or only brief in nature, administer additional reversal agent as directed by the product’s prescribing information. Hemodialysis is not routinely used to enhance the elimination of hydrocodone from the body. Physostigmine may be used parenterally for the treatment of the signs and symptoms of homatropine toxicity.
